Nano Labs Corp. has been issued a provisional patent number for its intelligent illumination greenhouse system, which works with commercial LEDs to reduce energy consumption and improve plant growth.

The new system reduces energy consumption while at the same time providing improved control over artificial light used to stimulate photochemical activities related to plant growth and chlorophyll production. Using a pulse modulated chlorophyll fluorescence monitoring stage, the technology allows automatic control of light in relation to a whole range of greenhouse and plant conditions, including seasonal adjustments tailored to the type of vegetables and plants being grown. The result is better control of light wavelengths, quality and pulse widths.



“The company’s proprietary technology represents an answer to problems facing greenhouse growers worldwide,” said Dr. Victor Castano, CEO of innovation at Nano Labs. “Our aim is to help growers increase efficiencies for better crop yields. At the same time, we want to help growers achieve lower energy consumption with a favourable impact on the environment.”


The system has allowed Nano labs to determine the effect of pulsed red and blue LED light in a frequency range from 0.1 Hz to 100 kHz on the chlorophyll fluorescence emission of tomato plants. Findings indicate that the system allows growers to control and enhance plant growth at will.


The provisional patent describes a smart, programmable lighting system that has a digital interface to program plant and crop specific configurations. Nano Labs is now moving forward with commercializing the system.
